you are rolling a 10-sided die with sides numbered 1-10. you keep rolling the die until you roll a prime number and then stop. l

evablogger [386]

The formula for E(x) would be SUM[ X(n)P(n)] from n = 1 to n = infinity until we get the prime number

In the given problem, a 10-sided die with 1-10 numbers is rolled until we get a prime number

Prime numbers between 1-10 = 2,3,5,7 (4 prime numbers)

Non - prime numbers = 1,4,6,8,9,10( 6 non-prime number)

Let X be the number of times the die is rolled

The probability of getting a prime =

$P(Prime) = \frac{4}{10}$

Now, the value of

E(X)=∑x.P(x) [ x-> {1, infinity}]

= P(1)X(1) +P(2)X(2)+P(3)X(3)+P(4)X(4)........+ P(n)X(n)

= 1. $\frac{4}{10}$ + 2. $\frac{6}{10}$ . $\frac{4}{10}$ + 3. $\frac{6}{10}$ . $\frac{6}{10}$ $\frac{4}{10}$ + 4. $\frac{6}{10}$ . $\frac{6}{10}$ . $\frac{6}{10}$ . $\frac{4}{10}$ .......

Hence, this is the value of E(x)

(x+y=3 (3x+2y=14 what is the coordinates for this problem

Ludmilka [50]

3x - 2y + 2y > -14 + 2y 

3x + 0 > -14 + 2y 

3x > -14 + 2y 

3x + 14 > -14 + 14 + 2y 

3x + 14 > 0 + 2y 

3x + 14 > 2y 

(3x + 14)/2 > 2y/2 

(3x + 14)/2 > y*(2/2) 

(3x + 14)/2 > y*(1) 

(3x + 14)/2 > y 

y < (3x + 14)/2 

y < 3x/2 + 14/2 

y < 3x/2 + 7 

y < (3/2)*x + 7 

“y” is LESS THAN (3/2)*x + 7 

the slope intercept form of the inequality is: y < (3/2)*x + 7 

STEP 2: Temporarily change the inequality into an equation by replacing the < symbol with an = symbol. 

y < (3/2)*x + 7 

y = (3/2)*x + 7 

STEP 3: Prepare the x-y table using the equation from Step 2. 

Using the slope intercept form of the equation from Step 2, choose a value for x, and then compute y for at least three points. 

Although you could plot the graph with just two sets of x-y coordinates, you should compute at least three different sets of coordinates points to ensure you have not made a mistake. All three x-y coordinates must lie on the same straight line. If they do not, you have made a mistake. 

You can choose any value for x. 

For example, (arbitrarily) choose x = -2 

If x = -2, 

y = (3/2)*x + 7 

y = (3/2)*(-2) + 7 

y = 4
